| Study Title | Impaired metabolism predicts coronary artery calcification in women with systemic lupus erythematosus |
| Study Summary | Background. Patients with systemic lupus erythematosus (SLE) exhibit a high risk for cardiovascular diseases which is not fully explained by the classical Framingham risk factors. SLE is characterized by major metabolic alterations which could contribute to the elevated prevalence of CVD. In order to address this hypothesis, a comprehensive analysis of the circulating metabolome and lipidome was conducted in a large cohort of 211 women with SLE who underwent a multi-detector computed tomography (CT) scan for quantification of coronary artery calcium (CAC), a robust predictor of coronary heart disease (CHD). Results. Beyond traditional risk factors, including age and hypertension, disease activity and duration were independent risk factor for developing CAC in women with SLE. The presence of coronary calcium was associated with major alterations of circulating lipidome dominated by a high abundance of circulating ceramides with very long chain fatty acids. Alteration in multiple metabolic pathways, including purine metabolism, arginine and proline metabolism, and microbiota-derived metabolites, were also associated with CAC in women with SLE. Backward stepwise logistic regression models of lipidomic and metabolomic variables were used to develop prognostic scores. Strikingly, combining metabolic and lipidomic variables to clinical and biological parameters markedly improved the prediction (Area under the curve: 0.887, P<0.001) of the presence of coronary calcium in women with SLE. Conclusion. The present study uncovers the contribution of disturbed metabolism in the presence of coronary artery calcium and the prediction of CHD in SLE. The identification of these novel lipid and metabolite biomarkers may help to stratify patients for reducing CVD morbidity and mortality in SLE. |
